Oswegatchie/5ponds is a nice trip... and the Adirondaks offer a lot of options as well but I've had mixed success and seems to be a lot of variance year to year. My favorite hike in brook trout fishing is in the Tunk Mtn. area of Maine and Downeast Maine in general. There are hundreds/thousands of oppt'ys to drive down endless logging roads and then hike into remote ponds, lakes, and streams.
I once knew a drug addict... He told me I have a fishing problem!
